The KCUR 89.3 transmitter antenna is located about 850 feet up this 1,100-foot radio tower in eastern Jackson County. KCUR replaced our aging transmitter in December 2021 after a successful ...

Discussions with FM engineers unearthed concerns about radio’s future when considered with reference to streaming, DAB/IBOC, RBDS, satellite radio, and new applications of some laws of electronics ...

Micrel Semiconductor has developed a single-chip radio transmitter for unlicensed bands in the 280 to 460MHz range that automatically corrects for differences in a connected loop antenna so the board ...

We think of radio navigation and direction finding as something fairly modern. However, it might surprise you that direction finding is nearly as old as radio itself. In 1888, Heinrich Hertz noted ...

The 47-year-old Voyager 1 spacecraft is back in touch with NASA — but not out of the woods — after a technical issue caused a days-long communications blackout with the historic mission, which is ...

A simple fm radio transmitter circuit which covers frequencies from 88 to 108 MHz. It is built with 3 transistors: BC109, BFR91A and BFR96S. It is quite stable and the output power is around 200 mW.

Whether slalom or alpine skiing, competitive skiing is all about thousandths of a second. Hence, professional athletes must constantly refine their technique. Small radio transmitters will make it ...

We examined whether surgically-implanted radio transmitters with percutaneous antennas affected behavior of Lesser Canada Geese (Branta canadensis parvipes) in Anchorage, Alaska. We implanted either a ...
